Reading achievement in the United States has stagnated. In 2009, only 33 percent of Fourth Graders were proficient or above in reading — a mere two percentage points higher than in 1998. At the same time, double-digit achievement gaps between African American and Latino/ Hispanic students and their white counterparts have changed little in nearly two decades. More troubling, there are few examples of system-wide success stories — school districts that have improved equity and overall student achievement. Montgomery County Public Schools (MCPS) in Maryland is one such example. Geoff Marietta documents MCPS and its PreK-3rd approach in this case study, Lessons for PreK-3rd from Montgomery County Public Schools.
